Application filed December 24, 1915. Serial No. 68,483.

To all whom it may concern Be it known that T, Jones F. STONE, a citizen of the United States, residing at Columbus. in the county of. Franklin and State of Ohio. have invented a certain new and useful Improvement in Fire Apparatus of which the following is a specification.

This invention relates more particularly to motor fire apparatus which carries a pumping engine and hose and the object of the invention is to simplify the construction whereby an economy of power and space is effected and the apparatus made steadier and more secure from overturning in running.

The invention is embodied in the construction herein shown and described and then pa rticularly claimed.

In the accompanying drawing-- Figure 1 is a general view in side elevation.

Fig. 2 is a side elevation on a larger scale of the rear portion of the chassis with the body removed.

Fig. 3 is a plan view of what is shown in Fig. 2

Fig. a is a sectional view of the pump and driving gearin associated therewith.

In the views 0 designates the frame of the chassis which is mounted upon the front wheels 6 and rear wheels 7. The vehicle is driven from the rear wheels. At 8 is the hood which incloses the gasolene engine which may be of any approved type. The operators seat is shown at 9. The steering wheel is designated 12. A gasolene tank 13 can be supported in the usual way in rear of the seat. A hose receptacle 14 is mounted on the frame in rear of the seat and is provided with a step at 15 and a hand rail 16. The step is within convenient reach of the ground and the hose receptacle is easily accessible to firemen standing on the step.

17 designates the main driving or crank shaft which is composed of two parts connected by a separable clutch at 19 as usual. of the car to a transmission and speed changing and reversing gearing designated generally by.

the character 18. This gearing is of usual or approved construction and needs no particular description here. The clutch 19 is provided with an operating foot lever 20 for disconnecting the parts of the driving shaft when. starting, changing speed, reversing or stopping.

Surrounding the main vehicle driving shaft between the clutch l9 and the transmission gearing 18 is a tubular shaft 21 carrying secured thereto impellers of a pump. These impellers work in a stati nary pump casing supported by suitable frame members in the chassis and having intakes 2% and outlets 25. T he tubular shaft 21 has suitable antifriction bearings at 253 and 2? in bosses on the stationary pump casing. it its forward end the tubular'shaf 21 is provided with a gear wheel l7 which is permanently engaged by a gear wheel 28 fixed to an auxiliary shaft casing 80. Keyed on the main driving shaft 17 is a gear wheel 31, and slidingly mounted on a splined portion of the auxiliary shaft 29 is spur gear adapted to he slid into and out of engagement with said gear wheel 31. Engaging a groove 32 in the gear 32 1s sliding fork 33 actuated by a crank arm 3% on one end of a shaft 35 mounted in a bracket 36. The other end of said shaft extends through and beyond the tubular shaft 37 and receives a hand lever -38 so that thegear 32 can be shifted by an operator while standing on the ground at the side of the apparatus. The tubular shaft 37 has connected with it a rod 37 extending rearward to actuate the speed changing gearing. The hand lever 38 works adjacent a latching sector 38 of ordinary construction.

The apparatus contains the usual controlling lever for working in the H slot at 39 for operating the gear shifts of the speed changing and reversing gears. l/Vhen the engine is operating and said lever stands in the neutral position and the clutch of the main shaft connects the parts of that shaft, said shaft is rotated but without transmitting power to thetractor wheels. To cause the prompt stopping of the drive shaft without stopping the engine the rear side of the sliding clutch member is provided with a brake member 43 that cooperates when slid rearward with a brake member 44: on the shaft. This construction is usual in motor vehicles for the purpose of permitting the shifting of the speed changing and reversing gears and similarly the arrange ment here described permits the shifting of the gear 32 into engagement with the gear 31 for operating the pump.

Among the advantages of this construction are that the pump, which is a heavy :29 in a suitable structure, is located between the front and rear wheels thereby distributing the load substantially equally on both; the center of gravity of the structure is placed low so that danger of overturning in rounding corners pose of permitting .the connection of the' propeller'shaft with the pump when the operator is standing on the ground, said shaft 42 is extended to the side of the apparatus where it is provided with a lever 45 for disconnecting the sliding member of the main clutch and sto ping the operation .of that portion of the drive shaft in rear of the clutch.

While I have shown the invention as embodied in a motorfire apparatus it can, of course, be used in other vehicles in which a pump is useful.

What I claim is:

1. In a motor vehicle pumping apparatus, the combination with the chassis having main longitudinal frame members, of a motor, main clutch for the vehicle, transmission gearing and propeller shaft disposed between the main clutch and the transmission gearing, a pump casing, transverse frame members supporting the pump casing between the main frame members of the chassis and disposed between the ends of the propeller shaft, bearings supported by the pump casing, 'a tubular shaft through which the propeller shaft passes ournaled rotatably in the bearings, an impeller for the pump carried by the tubular shaft and means for operatively connecting and disconnecting said tubular and propeller shafts.

2. In a motor vehicle pumping apparatus, a chassis having a motor, a transmission gearing, a drive shaft operated by the motor, a shiftable clutch device on said shaft for connecting the transmission with and,

disconnecting the same from the' drive shaft, said clutch being operable from the drivers seat and means whereby said shiftable clutch device may likewise be operated by aperson outside the vehicle, a pump having an im peller shaft, shiftable means for operatively connecting and disconnecting said impeller shaft, said shiftable means being operable from the drivers seat and means whereby the same may be likewise operated by a per son outside the vehicle.

3. In a motor Vehicle, the combination with the chassis, motor, main clutch for the vehicle changespeed gearing, and propeller shaft interposed between the clutch and the gearing, of a tubular shaft through which the propeller shaft passes loosely, means for mounting the tubulalxshaft rotatably on the chassis, a pump connected to said tubular' shaft with the propeller shaft independently of the vehicle driving means.

, 5. In a motor vehicle, the combination with the chassis, motor, main clutch for the vehicle, change-speed gearing and propeller shaft interposed between the clutch and the gearing, of transverse frame members supported by the side frame members of the chassis and disposed between the clutch and said gearing, bearings carried by said transverse frame members, a tubular shaft mounted rotatably in said bearings and through which the propeller shaft extends loosely, a pump carried on the frame members and connected operatively to the tubular shaft, and clutch elements disposed be tween the tubular shaft and the propeller shaft.

6. In a motor vehicle, the combination with the chassis, motor, main clutch for the vehicle, change-speed gearing, a propeller shaft disposed between the main clutch and the gearing, of transverse frame members extending between the main frame members of the chassis and located between the ends of the propeller shaft, bearings carried by the transverse frame members, a tubular shaft mounted rotatably in the bearings and through which the propeller shaft extends loosely, a pump casing carried on the transverse frame members, a rotor for the pump carried by the tubularshaft, and independent clutch devices operatively interposed betwefen the propeller shaft and the tub ular sha t.
